New version - NOT as good as the predecessor versions. Osprey changed the side pockets, which now have a difficult time accommodating a Nalgene 1 liter bottle. More importantly, they changed the way the frame height and shoulder straps adjust. They discarded the perfectly functional velcro scheme, which was infinitely adjustable (within the overall limit) and substituted a mickey mouse tabular scheme. This reduces the overall height adjustment available (so if you're 5'11" or more, be careful) and changes the feel of the pack on your shoulders. This change, as well as the side pockets, are detrimental to the overall utility and feel of the pack. Fortunately, I have a few other legacy Osprey 34 and 36 packs, so I'll live, but this is a disappointment.

It performs great on the technical side of things--hiking, climbing, and for such a small pack it carries heavy loads with ease. The suspension is excellent as to be expected by Osprey, and the pack back breathes really well (my back stayed cool while others in my group were drenched in sweat). It's also made of more durable materials than your average technical pack which was appreciated when shoving the pack on the various cramped forms of local public transit in Tanzania. The pockets are excellent, allowing for great organization and are super well placed.

It fits in overhead bins due to the narrow profile, but wouldn't be my first choice for travel unless your trip has technical objectives. This is because the frame prevents you from packing the bag down even smaller, and adds size to the pack but not internal volume. I wish the brain and hip-belt were removable but the frame prevents you from making the pack much smaller anyway.In conclusion an excellent pack in terms of performance, and lot's of great organization that's actually very intuitive and useful. Perfect for backpacking, thru-hiking, milder mountaineering, cragging, and as an awesome and flexibile general purpose bag in this size. The suspension, hard frame sheet, and durable materials means it can carry whatever you can throw into it and you don't have to baby it like you would a more lightweight pack. That being said, it wouldn't be my first choice for alpine climbing or travel (unless your trip involves lot's of outdoor pursuits) because the frame style makes the pack relatively bulky for its size, and you can't strip the pack down and remove things like a good alpine pack; however it's not marketed or designed for these activities. Great pack from a great brand.

My main goal with buying this was a bag to carry all my current climbing gear and also be able to do some basic overnight trips or lightweight summer backpacking.I compared this to the Gregory Zulu 30 and Dueter ACT Trail 30, ended up going with the Osprey due to better in-store comfort, brand loyalty, and I was able to get one for cheaper than the other two.So far I've had the pack a week so my review is mainly going to be more of an initial thought.What it fits:1x Black Diamond Solution Harness with an ATC+Carabiner, Grigri 2+Carabiner1x Mammut multipitch chalk bag2x climbing shoes (Scarpa origin and force v)6x Petzl quickdrawsvarious anchoring gear (2x 120cm slings, 2x 30cm dyneema slings, 2x 6m prusik loops, 1x 7m cordelette, 1x metolius pas ... MoreMy main goal with buying this was a bag to carry all my current climbing gear and also be able to do some basic overnight trips or lightweight summer backpacking.I compared this to the Gregory Zulu 30 and Dueter ACT Trail 30, ended up going with the Osprey due to better in-store comfort, brand loyalty, and I was able to get one for cheaper than the other two.So far I've had the pack a week so my review is mainly going to be more of an initial thought.What it fits:1x Black Diamond Solution Harness with an ATC+Carabiner, Grigri 2+Carabiner1x Mammut multipitch chalk bag2x climbing shoes (Scarpa origin and force v)6x Petzl quickdrawsvarious anchoring gear (2x 120cm slings, 2x 30cm dyneema slings, 2x 6m prusik loops, 1x 7m cordelette, 1x metolius pas 22)various personal things(camera, sunblock, snacks, etc..)With all of this loaded, I do have some extra space for small things to pack in/down the sides but not much else, but I also don't have it packed the most efficiently, I just threw everything in to see if it would fit and it does. Currently I keep my harness/chalk bag on top, shoes underneath that, and everything else under that since I mostly climb at the gym.In terms of rope, I don't have one to test with (my friend bought a rope already, I'll get one... eventually), but I imagine you could either fit it to the top and use the top compression straps to hold it in place, or use the sleeping pad straps to carry it on the bottom, though this would potentially get your rope dirty if you set your pack down a lot.I haven't tried loading it with my 2.5L platypus hydration along with the rest of the gear yet, but I have no doubt it'd fit once I reorganize it a little, currently everything is just shoved in there, a testament to the amount of space you get.My thoughts: Fits me great, very comfortable for the short times I've used it, I quite like the outside pockets, the hip pockets will fit my LG V20 with some coercion, the back panel is supremely comfortable and airy, perfect for the hot Californian summers.Biggest flaw currently is that the bottom sleeping pad panel is not removable, though you can unhook it and let the main compartment take up that space.Still disappointed I can't access my pack from the bottom, that was a great feature in my Aether.I've yet to try this pack while Hiking and will update once I get some miles in.

Very comfortable pack. Fully loaded with a 3L bladder, lunch for 8, and a sweatshirt, it carried great for 7 miles through Canyonlands NP. I actually returned it though to trade for the Stratos 24L pack because the frame is about 2 inches shorter. I wanted to use it for my under-seat carry-on bag and the 34 sticks out too far.The pack setup is pretty good. I wish the small stash pocket at the front top was a little larger and had a soft lining to better accommodate sunglasses. The mesh top pocket also hangs down inside and makes getting your water bladder strapped in difficult. The hiking pole holder works great. Waist belt pockets could be bigger; it’s hard to fit an iPhone 13Pro inside.
I really like the Osprey Men's Stratos 36 Pack. This is not the first I've had. I sent the old one off to be repaired, but I needed one to hike with while I wait, so bought another. The new version seems smaller and after using three times and making adjustments I haven't figured out how to get it to fit correctly. Maybe I should have bought the larger pack, but hey, I am only 5'6".Anyhow the new pack has a new zip compartment on the back instead of two on the top, which is okay and allows a little more storage space. But the real drawback is the main compartment can only be accessed from the top. The older version had a zipper going up and around so you could open the whole space and not have to dig for the items on the bottom.This is the first time I sent an ... MoreI really like the Osprey Men's Stratos 36 Pack.

Very functional. Great weight distribution and air circulation for day hikes - I used it on ~10+ mile hikes. The compartments are placed in an awesome way, especially the ones on the waist belt.The biggest drawback is the main sack compartment. I DO NOT like the width/diameter - it is rather narrow/small when it comes to packing or accessing items quickly. The alternate side access zipper for the main compartment does not solve the problem completely as it involves unbuckling one or even two of the click lock straps. This may be the only reason why I might exchange it for something else.I even used it for an international trip. Although it's not meant for carrying a laptop, it kind of worked if you don't think about the quick removal for security scanning. I ... MoreVery functional.

I know it was great because I did 2 similar trips within a short interval - I had the backpack on one trip only - and that made a huge difference. At about ~30lbs packed weight, long brisk walks in extremely busy and large airports I did a lot better when I had this backpack.Still a bit expensive for what you get - should be cheaper by about $30 IMO.Another drawback is you can never have it stand upright the way its shown in pictures when you put it down (which is the case with most hiking backpacks so not surprised) but it will fall forward on the dirt - so pray there be a tree for support :)Yet another issue - the mechanism to hold the pole is not great - but maybe I am doing it wrong.
Although larger than many packs promoted for day use, it is relatively light for a pack with a frame. I find the size to be perfect for "all day" hikes where I may be wearing different layers throughout the day and want to have ample food and water. The compartments allow me to quickly find what I need. The design is comfortable, and readily adjusted to distribute the weight well. My only complaint is that I cannot reach my water bottles without taking off the pack. I am usually with friends, or want to sit for a bit, so it hasn't been a major problem. There is room for a camelback, which would be another solution.
After 11 years my Marmot Zephyr finally got a hole in the bottom and got completely soaked while in Kalalau. It was time. I researched and picked this pack for my long day hikes (12-24 mi). It is a techie's dream - and extremely comfortable. It takes awhile to adjust to your exact torso, but once there, you barely know it's there. The air space works to cool my back, both side pockets work for decent water bottle carrying, also hold both poles while bouldering, the fanny pack pouches are larger and can hold wallets and/or snacks, there's one big pouch for food and 1 Gal+ of water, holds a 3L bladder, you can loop on a jacket or camping mat on the bottom, all the zippers come with big loops so you can feel and pull them while still on. It comes with a rain cover, and ... MoreAfter 11 years my Marmot Zephyr finally got a hole in the bottom and got completely soaked while in Kalalau. It was time.

(Update 2020) Finally used this pack as an overnight backwoods pack. It was an adequate size for one night. I went with my daughter with a child's Osprey pack. I carried the 2-person tent, clothing and her sleeping pad inside, and attached my bag and sleeping pad outside, along with a shovel, raincoat. The bottom pocket held most cooking gear. I agree with Shaun S. that "you must choose between filling the organizer pockets or filling the main volume". I was only able to put small flat items in any of the pockets with the bag stuffed.-------------------------------------------------------------------------------------------------With this bag stuffed and loaded at 30.5lbs total, it remained very comfortable for me.

I was only able to put small flat items in any of the pockets with the bag stuffed.-------------------------------------------------------------------------------------------------With this bag stuffed and loaded at 30.5lbs total, it remained very comfortable for me. I noticed the weight on the hike, but not discomfort in any one spot. The hip belt did its job and I didn't need to keep adjusting shoulder straps for comfort. The weight was not dispersed too far high and back like other packs I've owned. My back didn't sweat because the ventilated back panel did its job.------------------------------------------------------------------------------------------------------------------------------------------------Final opinion, I'm keeping the 5-stars with understanding that this is best suited as a day-pack and not stuffed to capacity. The Stratos 34 can be used for overnights, but if you're looking for that primarily, I'd look at a different design that gives slightly more volume with pockets more suited for that purpose.################################################ Initial review (2017) ################I purchased this bag for the purpose of a large daypack. It could be used as a minimalist overnight pack, and I plan on trying it at least once. My main goal was for holding a DSLR camera and large lens in the main compartment, tripod on the outside, rain gear in the bottom compartment, cell phone and small gear in the belt pockets, plenty of water, snacks, first aid kit, etc in other compartments. It does all this very well with room to spare. ----------------------------------------------------------------------------------------Though not specifically designed as a camera backpack, this pack gives quick access to the main compartment, especially compared to similar sized packs with the popular top compartment above a drawstring. Unlike camera backpacks, it has room for all the other day-packing stuff you may need. The torso height on the Medium/Large Stratos 34 can be adjusted to accommodate my height (72"), torso height (20"). Torso adjustment is maxed out, so the 21" max toro height might depend on a person's build.-------------------------------------------------------------------------------------------------------------------------I've used it a few times and here are my observations: The construction seems solid; my back didn't get sweaty; the weight distribution felt great, with the majority on my hips; the hip pockets worked fine for a medium cell phone; there were no squeaks from materials rubbing inside the pack (silence is key when out in nature); the water bottles were accessible without taking the pack off--for me anyway. I don't plan on using a hydration system, so no comment there. The main compartment zipper works mostly well except around the top corners. It doesn't snag in the surrounding material, but the zipper cover slows it down a bit. I sometimes flip it back when using. The lower pocket is perfect for rain gear or layers, but is designed for a sleeping bag. Only a higher temp, very compressible down bag might fit, as the compartment is pretty small. ---------------------------------------------------------------------------------------Overall I love this bag for my purposes and plan on really putting it to the test. If you're looking for a minimalist overnight backpacking pack, then know your gear and what 34 liters is, and if unsure, chat with customer service for details before buying.
This pack is great! My husband used it for the first time today and didn’t have one complaint during our 11 mile hike. It packed his rain gear, food, 4 liters of water and other misc gear just fine with room to spare. He was very please with how comfortable the pack was and he also appreciated the different straps to get the pack more customized to his body. His big backpack we use for multi day hikes doesn’t have a frame, well a minimalist frame if you will, and so he appreciated this backpacks structure. He loves the blue color as well. It has plenty of different places to stuff little things here and there and he also likes the rain cover that is included. It has its own little pocket at the bottom of the pack. Great bag for long day hikes !
